Delhi recorded its worst air quality of the year the morning after Diwali as the pollution level entered the "severe-plus emergency" category due to rampant bursting of toxic firecrackers, authorities said.

People in several cities burst firecrackers until at least midnight, two hours after the 10 pm deadline set by the Supreme Court.

Partly as a result of smoke from the firecrackers, the overall air quality index (AQI) in Delhi jumped to 574, which falls in the "severe-plus emergency" category, according to data by the Centre-run SAFAR (System of Air Quality and Weather Forecasting And Research).
